. 1;697,603V V G. LAPIERRE l MACHINE Fon PASSING TAPE THROUGH HooKs Filed oct. 1927 2 Sheetsfsheet 2 @ORNE/ v v nected string 5,8 moves the scissors tocut the Y having a stationary member 60. Spring 61 main open.

bracket has an velongated aperture 65 and pliers 66 arranged to be slidable and turnable therein. l

The operation of the device consists in clamping hook 67 in the pliers, moving the Apliers so that the hook coincides with split 63, shown in dash-dot lines in Fig. 1. Next,

the handle lever 45 is moved to engage the clutch 43 and the wheel 42 should be driven by driver belt 68,. Thus, shaft 39 is caused to rotate. The arm 40 moves clockwise as viewed in F ig. 3 so that roller 41 permits the arm 37 to raise and the spring actuated drum draws cord 22, moving the hook 19 towards the right. The hook 19 is provided with a projectingpeg 70, which passes over cam 62. Asthe arm 40I continues its motion Yit next presses the arm 37 downwards, and this motion is transmitted through arcuate armv 36 and the gears to the drum 28 which draws Vstring 22 thereon, moving the hook 19 towards the left.V The peg 70 now travels beneath the cam 62 and the hook 19 is forced Vinto the'end of materia-l 14 and then draws the material across the machine, over the hook 67- aligned over split 63. The hook 19 is provided with an equilibrium spring 69 lto keep'it in neutral'position'. y n

As thershaft 39 turns, .thearm 46 with Vroller47 forces the arm 37 downwards, ldrawingv oord 48 downwards, and vforcing fingers 52 to pushthematerial 14 through the hook. The arm 56 moves 37a downwards, and 'conf material. The lhook 67 with a piece of material 14 looped through the holesthereof l,may be removed from the machine, and anotherhook inserted in the pliers and fed to the' machine. `Themachine may be stopped bylmoving lever to disengage the clutch v While `I have illustrated and described the y ln'eferredV form, construction', and arrangement of the several elements employed, it

will be understoodthat the device is neverone end of the frame, a cord secured to the drum, the drum normally tending to wind the cord thereon, idler pulleys arranged on the frame, a second drum fixed to ashaft rotatably mounted, the said cords passing over the idlers and the'end being secured to n the drum, a rod connected to the frame, and arranged parallel to a portion of the cord, the

sai-d rod being formed with a groove, a member slidably arranged in the groove, an' arm connectingthe member and'cord, the last mentioned drum being arranged for rotation inone direction and then in the other so as to reciprocate the member in the groove, a

hook pivoted to the member, and means for causing the hook to engage tape material at one end of the stroke of said member in the groove, so as to draw the tape as the member returns to its other endof the groove.

2. In a machine of the class described, a frame, a spring operated ydrum arranged thereon, a. lcord secured to the drum, the drum normally tending to wind the cord thereon, idler pulleys arranged on the frame, a'second drum fixed to a'shaft rotatively mounted, the said cords passing over the idlers and the end being secured to the drum, a rod connected to the frame,` and varranged parallel to a portion of the cord, Ya member slidably arranged on the rod, an arm connecting the member rand cord, means for rotating 'the last mentioned. drum in one direction yand then in the other so as to reciprocate nthe member along the rod, a hook. pivoted to the member and means forcausing the hook to engagel tape material at one end of the stroke 5 of saidmember along the rod, so as to draw t-he tape as themember returns to its other 105 end of the rod. v

In ,testimony whereof I have aiixed my signature.
